Read array from a file

readarray name

Reads in and returns an array from a file with the specified name. Each line in the file becomes an item in the array. Empty lines are omitted. If a line consists of multiple words (separated with white spaces then) a subarray of words is created and added as an item to the array. If at least one item in the array is a subarray then all other items which are not yet arrays are converted to single-item arrays.

If the name does not contain an absolute path then the file is assumed to be in the current directory, specified with the :pool_cfg,"current_dir variable.

The name can be also a http adress.
